Checker 440 Verified ((hot)) — Psa Interface
Connect the Lexia or PP2000 interface to the computer using a standard USB cable. It is not necessary to connect the interface to a vehicle during this process. The system should automatically detect the interface and install the appropriate drivers. Using a direct USB connection to the computer—rather than passing through a USB hub—is recommended to avoid connection issues.
Fourth, use a stable computer with a clean Windows installation dedicated to diagnostic work whenever possible. This minimizes conflicts with other software and reduces the likelihood of driver problems.
Deep down, the "PSA Interface Checker 440 Verified" is a monument to human humility. It is an admission that we, as developers, are incapable of holding all states of a concurrent system in our working memory. We need a mechanical, pedantic, tireless assistant to check our work.
: Confirms the current firmware version (e.g., APPLI_V4.4.0) to ensure compatibility with DiagBox. Hardware Revision Identification : Determines if the device is a Revision B Revision C

The is a specialized, lightweight application often bundled with Lexia 3 software packages. It is designed specifically for Chinese clone Lexia interfaces. Unlike genuine Actia interfaces, clones often face issues during Diagbox updates, where they may lose communication or become "bricked." Key Functions of the Interface Checker:
Instantly reads whether your adapter is recognized as Revision B or Revision C.
Displaying the current firmware (e.g., 4.2.2, 4.3.0, 4.3.3). Connect the Lexia or PP2000 interface to the
: If Diagbox updates the firmware to a version that causes the interface to stop working (a common issue with clone devices), the Checker can downgrade it to a stable version like 4.2.4. Understanding Hardware Revisions (B vs. C)
If the flash to 4.4.0 completes smoothly but you cannot read specific modules (such as the BSI or airbag), your VCI hardware lacks the physical internal components required to parse those specific CAN bus lanes. You will need to upgrade to a confirmed full-chip physical interface. To ensure your diagnostics system functions seamlessly, Find out where to download stable DiagBox VM images ?
Often considered the most stable "Gold" firmware for standard clones (Reference "B" or "C"). It provides a reliable balance of compatibility with both older Peugeot/Citroen models and the newer Diagbox 7.x - 9.x series.
For users who need to verify or update their diagnostic interface, the following step-by-step process provides a reliable path to success. Using a direct USB connection to the computer—rather

An interface that is has been tested and confirmed to behave exactly like an authentic ACTIA XS with firmware version 4.4.0 or equivalent. This verification is crucial because many sellers list “compatible with DiagBox” but their hardware fails when deep ECU coding (like injecting a new BSI or programming a key) is attempted.
and wait for the "OK" status or for the green LED on the VCI to blink. Why "Verified" Status Matters A "verified" PSA interface usually refers to a "Full Chip"
The "Verified" status typically means the tool can see the serial number and version, indicating the device is ready to connect to a car.
